Chapter 1422

Looking at the window outside, Chen Rui can see that this is everything he used to be familiar with. The runway of factory 1132, right on the side of the apron, can see the beautiful fighter. Its main wing is behind and the duck wing in front, which makes it look very energetic.

Once, Chen Rui was the test pilot of the plane. Later, he was asked to leave by the navy to simulate the takeoff and landing of the aircraft carrier.

Now, seeing this plane, Chen Rui is also very kind.

"Xiang Jing, Andrew, you and Yutong, Xiaoxia, Xiao Lu and others will go to the hotel first. It's very late today. We'll go to the city tomorrow. The scenery here is also very beautiful," Qin Guan said.

After getting off the plane, there was a car to greet him. After seeing off the others, Qin Guan took the scholar and Chen Rui and went straight to the apron.

"It's a little different." from a distance, Chen Rui saw the clue. Then, Chen Rui suddenly found something: "its engine has been changed."

In the past, this fighter used the Spey engine. Although it has been modified and improved its power, it is already the limit. Its aerodynamic layout is very advanced, but it is often dragged down by the engine.

Now, when he approached, old song and others welcomed him.

"Mr. Qin, thank you for bringing us the engine." Mr. Song said.

Relying on the last incident, after the negotiation, the eagle country provided a number of engines. Most of these engines were robbed by the Navy. They wanted to use them on their J-11 fighters. Here they were divided into five. After they got them, they quickly matched them. Now, they finally put them on this J-10 fighter.

Spey engine, the thick outer nozzle, is fixed, can not perform any action, and only plays the role of rectification. The inner layer can perform small-scale convergence action. In fact, this double-layer nozzle has long been out of date. The nozzle of the current three generations of engines can converge and expand as a whole, which can effectively improve the efficiency of jet.

Now, if you look from the outside, Spey's nozzle is a cylinder, while the engine in front of you, with the nozzle backward, is in a retracted state, which looks different.

"I have to thank Chen Rui for this," Qin Guan said with a smile. "Without that good thing, how could we get this kind of engine."

Eagle people are very cunning. They only give dozens of engines and carry matching gas flow and other information. However, they don't give any technology. In this case, Han country will have to ask Eagle country for help in the future.

Of course, they will not know that they are already developing a new third-generation engine. This wholesale motivation is only temporary and just makes up for this shortage.

"Chen Rui, do you only find that the engine has changed?" Qin Guan said to Chen Rui.

When Chen Ruigang first started, he stared at the engine. After all, Chen Rui knew that there was a short board of the J-10. As long as the engine was changed, the performance of this fighter could be really brought into play.

Now, hearing what Qin Guan said, Chen Rui finally began to focus his attention on more places. Now he saw that there were some differences in front of it.

In order to improve the maneuverability at high angles of attack, it adopts the belly air inlet, and the inlet adopts an adjustable rectangular air inlet. In this way, it can provide excellent air inlet capacity at various speeds, which is a must to pay attention to the air combat interception capability.

Now, the baffle on the air inlet is gone, and the six sticks are gone. What Chen Rui sees is a big drum bag!

Qin Guan also stared at this thing with appreciative eyes. Unexpectedly, they had mastered the technology of this air inlet.

The scientific name of this kind of thing is the supersonic inlet without boundary layer partition. It has been used on the Xiaolong fighter. However, it doesn't just get a drum. It requires complex hydrodynamic calculation. Our current computer capability has been reached, and the old song actually used this technology on the J-10 fighter. In later generations, This is the standard of j-10b.

The drum air inlet has many advantages, such as simple structure, light weight, low resistance and improved invisibility.

Compared with the previous adjustable air inlet, it can save more than 50% of the weight. For the fighter, the lighter the weight, the higher the mobility. At the same time, this drum will block the air inlet blades of the rear engine, which can simply improve the stealth ability.

Of course, it also has some disadvantages. Although it has been optimized repeatedly, it has no adjustable ability after all. It can not achieve the best air intake at all speeds.

Compared with those advantages, the only disadvantages are acceptable. Moreover, there is already such a high thrust engine. "Mr. Song, is there a test flight today?" Chen Rui said. He couldn't wait.

After getting a positive answer, Chen Rui quickly ran to the pilot preparation room and soon changed a set of flight equipment from there.

Chen Rui hasn't flown since he forced to land the other party's plane last time. For a proud man of the blue sky, this is simply intolerable. Therefore, Chen Rui has wanted to fly for a long time. Unfortunately, his brother-in-law's meaning is very obvious. I'm afraid he didn't want Xiaoxia to fly before her stomach bulged. Now, I finally have this opportunity, He wanted to fly at once.

He was carrying a flying helmet in his hand. At this time, he didn't climb up the cockpit immediately. He said to old song, "what's the shelf on this helmet?"

He has found that there is a metal plate on his helmet with a card slot. It seems that he can add other things?

"Helmet sight?" Qin Guan said: "it seems that our research and development in avionics will finally surpass the world advanced level."

Qin Guan recognized it at a glance. In later generations, it is also a mysterious thing to say.

Helmet sight, as the name suggests, is a aiming device combined with the pilot's helmet. It is composed of helmet, display, head position measuring device and airborne computer system.

Its most important is follow-up, that is, where the pilot's head rotates, he can stare where he arrives.

Specifically, after the pilot finds the target, he can track the target by staring at the target through the signs in the display; The head position measuring device is used to measure the rotation angle of the pilot's head to obtain the angular position of the target relative to the carrier; The computer converts the target position information into aiming instructions and controls the missile's seeker, turret, radar or other photoelectric detection devices to track the target.

The helmet sight has the advantages of simple use, rapid aiming, convenient visual search and large tracking range. It is suitable for launching guided weapons or positioning and tracking of radar and photodetector.

Therefore, after its emergence, it is considered to be a change. In later generations, it is first equipped with the imported Su-27 series fighters. However, pilots do not use it very much in training, so there is only a shelf on their helmets. Anyway, the aircraft does not hang missiles, and it is useless to carry it. However, it will be carried when cruising in actual combat.

Now, Qin Guan didn't expect that his side already had this kind of thing.
